Touch panel capable of wide-area inputting

Abstract

There is provided a wide range-inputable touch panel and allowing a larger amount of input operations to be made with one display operation on a screen, in which at least one bus bar and a transparent electrode on a conductive panel fronting the bus bar though spaces formed in an adhesive layer cut out from an outer edge side thereof face each other so as to be capable of making electrical contact with each other by a press.

Description

[0001] The present invention relates to a touch panel allowing a larger number of input operations over a wide area, in which an additional input section from which input operations can be executed may be formed in addition to a screen indicating input section from which input operations can be executed according to indications on a screen.[0002] Touch panels that have conventionally been used in electronic notepads, personal computers, and the like include ones of analog resistance film type. In a touch panel of this type as shown in FIG. 11, ordinarily, two conductive panels 4, 5 having a pair of parallel bus bars 43, 53 and a transparent electrode 42, 52 formed between the bus bars 43, 53 on one surface of a transparent insulating base 41, 51 are made to face each other and are stuck together with use of a circumferential insulating adhesive layer 6 so that the bus bars 43 and 53 are arranged rectangularly. Each of the conductive panels 4 and 5 has a routing circuit 44, 54 connec...

AI Technical Summary

Problems solved by technology

The enlargement of the area in which the transparent electrodes face each other, however, has a limitation and there is a necessity for new measures to make it possible to form additional input sections from which input operations can be executed in addition to a screen indicating input section from which input operations can be executed according to indications on the screen and to make a larger number of input operations possible.
